To all whom t may concern.- andthe other orhooked end e bearing against Be it known that we, FRANK H. CLARK, rethe coupling pin C. The form, dimensions siding at Saratoga Springs, Saratoga county, and material of the bell crank D andlever E and ROBERT C.

Some means is therefore desired which left (Fig. l).

We thus provide ally, we accomplish this object by providing what may be called an emergency device the couplerwith suitable mechanism adapted, for uncoupling the coupler and preventing when the coupler is torn from the car, to enaccidents; and While we have described more gage with the locking pin to release the hook or less precise forms, we do not intend to 25 to unlock the coupler, and afterward to susunduly limit ourselves thereto, but contemt-ain such coupler and prevent its falling upon plate changes in form and proportion, and the track. the substitution of equivalent members as Our invention consists in the features, demaybe desirable or necessary.

In a coupler provided with a locking pin, to the draw head, at any suitable point, a lethe combination of a bell crank lever pivoted ver or hook E, preferably made in the form to the draw head, a chain attached to one arm Ico 5o shown, one end of this lever e being in enof such lever andto the car, and ahook lever gagement with the arm d of the bell crank, pivoted to the draw head, engaging with the other arm of the bell crank and with the coupling pin, substantially as described.

3. The combination with a draw head .provided with a rotating hook and a locking pin, of a bell crank lever pivoted at one side of the draw hcad, with the arms of the lever extending in substantially horizontal and vertical'positions, a chain attached to the car and to the vertical arm of the bell crank, a hooked lever pivoted beneath the draw head, one arm of such lever engaging with the horizontal arm of the bell crank and the other arm im pinging against the lower end of the locking pin, whereby when the coupler is' detached from the car, the chain will act on the Verti- 15 cal arm of the bell crank lever to rock the hook lever and raise the pin to release the rotating hook, thereby uneoupling the car, after which the chain will act to sustain the coupler and prevent its falling upon the track, zo substantially as described.
